. LAWRENCE M; TAYLOR, OF MULVANE, WEST VIRGINIA: GAGE FOR SAW-TEETH.

Specification of Letters Patent.

Application filed July 24, 1906. Serial No. 327,572.

To a whom it may concern:

Be it known that I, LAWRENCE M. TAY- Lon, a citizen of the United States, residing at Mulvane, in the-county of Fayette and State of West Virg'nia, have invented certain new and usefulrlmprovements in Gages for Saw-Teeth, of which the following is a specification. q

' The present invention relates to an improved gage for saw teeth by thev use of which the ,teeth of a saw can beaccurately best possible con dition for the most eflicient service. a

The gageis designedso as to be employed. in connection with any of the common forms of sawsand consists essentially of a body por-' tion fitting against one face of the saw, and a peculiarly constructed gage plate adjustably connected to the body portion and fitting between the teeth of the saw, the outer end .of the gage plate being beveled on an angle corresponding to the required angle of the tooth. This gage .is adapted to be held in position upon one side of the saw, whilea file is em ployed upon the opposite side of the saw to bring the side of a tooth down to the beveled end of the gage plate.

For a full understanding of the invention and the merits thereof and also to acquire a to 1n mpanying drawings, in

knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and 9.0-"

which:

Figure l is a side elevation showing the application of the device Fig. 2 is a top plan view of the same; and, Fig. 3 is a perspective. view of the saw tooth age.

Corresponding'and ike parts are referred the following description and indicated in all the views -of the drawings by the same reference characters." v

The numeral 1 designates the body portion of the saw tooth gage which is preferably inthe form of a bar adapted to fit against one of the faces of the'saw and provided upon-one side withthespaced lugs 2. These lugs form bearing points for the bar 1 and hold the same shghtly spaced from the saw and in a fixed position with relation thereto. The gage .plate 3 is adjustably connected to one end of the-bar 1 so as to be moved back and forth according to the width it is desired to. impart to the saw teeth. This adjustable connection is accomplishedby means of a longitudinal slot 4 formed in the gageplate and through which the"clamping screw 5 passes by means of whi secured to the body portion This gage plate 3 fits between the teeth of the saw when in use and has the outer end thereof beveled as seen at 6 on an angle correspond ing to that which it is desired to impart to the sidesof the saw teeth. In 'order to hold the gage plate in a steady position and to prevent the same from any lateral movement when in position between the teeth, projecv Patented may 28, 1907.

oh the gage plate is tions 7 are formed .upon opposite sides'thereof which are adapted to engage with the eX- tremities of the two teeth between which thegage plate is placed. In the preferred construction, these projections 7 are formed by means of a pin which is passed through the plate and extends outwardlyupon opposite sides thereof. In the will be observed that the gage plate has a width somewhat greater than the depth or length of the saw teeth and extends outwardly somewhat beyond the same. While this feature is not necessary for the proper working of the invention, it somewhat facilitates the formation of the projections 7. By setting the gage plate in the the teeth can be dressed down to any desired width. In order that this may be uickly and accurately accomplished, a scale 8 is formed upon the gage plate, in the present instance adjacent the slot 4, and a pointer or indicator 9 is placed upon the bar 1. It will thus be seen that all that is necessary in setting the tool is to move the gage plate upon the bar 1 until the pointer 9 indicates upon the scale S'the desired width of tooth. Y In the application of the tool, the body portion 1 is placed against one face of the saw to be dressed so that the ga e plate 3 fits between two adjacent teeth 0 the saw as indicated in Fig. 2. While the gage isthus held in position, a file is applied to the opposite sideof the saw down flush with the beveled portion 6 of the gage plate. It might be mentioned here that in the practical construction of the gage, the plate 3 is preferably formed of metal so as to resist the action of a file. After one side of the tooth'has been dressed, the gage is placed in position against the o posite face of the saw and the opposite Side of the tooth dressed in a similar manner. It will thus be understood the teeth of the saw are not only brought down to a, uniform width or spread, but are brought accurately in 'alinement with each hardened that with this gage,

present instance, it

proper position,

other and the sides of the teeth a're beveled from the extremities, thus placing the saw in the best possible condition. Owing to the fact that thegage is in position during the filing operation when the tooth is brought down flush with the beveled portion 6, much less time is required than where the gage must be removed while the teeth are being Having thus described the invention, what is claimed as new is:

' face of the saw; a gage plate projecting laterally from the body portion and adapted to fit I between the teeth of the-xsaw, the said gage j plate having itsouter end lie-yeled on an an gle corresponding to theangle for; the saw teeth, and atransverselydisposed pin passing through the gage plate, the ends of the plate and being adapted to engage with the inner edges of adjacent saw teeth to prevent any lateral movement of the gage plate. In testimony whereof I affix my signature in presence of two Witnesses.
